Assigning the AS-i slave address
In an AS-i network, each device is assigned an AS-i slave address. This address can range
from 0 through 31; however, address 0 is reserved only for new slave devices. The slave
addresses are 1(A or B) to 31(A or B) for a total of up to 62 slave devices.
"Standard" AS-i devices use the entire addresss, having a number address without the A or
B designation. "A/B node" AS-i devices use the A or B portion of each address, enabling
each of the 31 addresses to be used twice. The address space range is 1A to 31A plus 1B to
31B.
Any address in the range of 1 - 31 can be assigned to an AS-i slave device; in other words, it
does not matter whether the slaves begin with address 21 or whether the first slave is
actually given the address 1.
